This report details the findings from visual inspections conducted on two Austroads sprayed seal field trials: a non-modified binders trial near Gisborne,
A mobile pavement surface wear rig has been constructed, which aims to gain an improved understanding of the failure mechanisms that are particular to the pavement surfacing layer – as distinct from the structural layers – that may be caused by…
This report provides asset managers with practical guidance in the development and delivery of effective resealing programs. It builds on accumulated experience of previous studies and a review of sprayed seal performance throughout Australasia.

Austroads established its long-term pavement performance (LTPP) project in 1995. Over the last few years, a significant number of sites have been removed from the study due to pavement rehabilitation and road improvement programs.
This report…
This report summarises the activities undertaken during the 2012–13 year for a long term Austroads pavement monitoring project.
Austroads project AT1064 Long-Term Performance Monitoring to Develop Consistent Performance Models was originally…
This report documents the process of assembling and reviewing the RMS NSW cracking data and the analysis of this data and its associated variables of climate, traffic load and pavement strength which has led to the development of a potential road…
The work documented in this report demonstrates the use of existing Austroads deterministic road deterioration (RD) models in a probabilistic approach to estimate the possible predictions for the dependent variables of these models. This approach…
This report provides a brief state-of-the-art review of current traffic speed deflectometer (TSD) practice based on information gained from attending the deflection at road traffic speed workshop held in the UK in June 2012.
The current state of…
Bitumen, an important component used in road construction in Australia and New Zealand, is manufactured from a finite, non-renewable crude oil resource. A number of commercially available alternative binders and bitumen extended binders have been…
